A good meeting changes who does what next.
A room full of smart people can discuss the same unresolved problem for weeks. The meeting feels productive because everyone contributed, but nothing about the work has changed.
Try ending the conversation with three written lines: the decision, the owner, and the moment it will be revisited. If nobody can write those down, the group probably did not decide.
Make the action small enough to start before the calendar fills again. It is easier to learn from one real test than another hour of plausible ideas.
